FYI, following is a press release from the Turkish Embassy in Washington
DC. I found it at It is not copyrighted, please feel

Personally, I feel strongly that Birgenair should sue the German Goverment
for the premature early negative press exposure.




Washington, D.C., June 20, 1996 -- The U.S. National Transportation Safety
Board has determined that the crash of Birgenair 757-200 after takeoff from
the International Airport in Puerto Plata, Dominican Republic on February 6,
1996, killing all 189 passengers and flightcrew, was the result of a
mechanical deficiency. The Safety Board's findings run counter to the hasty
conjectures first alleging that the inexperience of the Turkish airline's
pilots contributed to the tragic accident.

Information recovered from the cockpit voice recorder (CVR) and flight data
recorder indicates that the pitot static system aboard the accident flight,
which is responsible for calculating airspeed, transmitted an erroneous
airspeed indication. It is evident that the discrepancy in airspeed led to
much of the confusion in the cockpit that preceded the accident.

Initially, hasty accusation claimed that had the captain activated his
alternative data source during the accident flight, it would have removed
the erroneous airspeed indication and prevented the subsequent stalling of
the aircraft. The Safety Board, however, found that Boeing Commercial
Airplane Group's Operations Manual for B757 did not contain procedures
either to identify an erroneous airspeed indication or to select the
alternate air data source as a corrective maneuver.

Moreover, the Boeing 757 EICAS system that provides alert messages to advise
the pilots of system failures and non-normal operational conditions does not
produce a message to alert pilots regarding an unreliable airspeed

The Safety Board recommended that the Federal Aviation Agency stipulate that
Boeing revise its B757 flight manuals to alert pilots to the conditions that
forewarn an erroneous airspeed indication, and include a detailed emergency
procedure addressing the identification and elimination of an erroneous
airspeed indication. In addition, Boeing should modify the crew alerting
systems of the B757 to activate a "caution" alert when erroneous airspeed is
detected. Already, such measures have been adopted by American Airlines and
Delta Airlines.

It is expected that as the principal commercial airlines manufacturer,
Boeing will incorporate any and all safety precautions, no matter the cost,
so as to avoid future tragedies.
